ABSTRACT OF THE DISCLOSURE
A cap is provided for use in closing a con-
tainer such as a bottle or flask having a threaded neck which
includes a conical ring converging outwardly and a radial
shoulder at an inner end of the ring. The cap is threaded
internally for engagement on the threaded neck to move the
cap over the neck into an engagement position thereby closing
the container. The cap also defines a radial recess positioned
such that the recess lies adjacent to and inwardly of the
shoulder with the cap in the engagement position. Also, the
cap includes a tamper-proof ring engaged in the recess and
adapted to pass over the conical ring when the cap is moved
into the engagement position. At least part of the tamper-proof
ring is adapted to be trapped about the neck and against the
shoulder upon removing the cap to give a visual indication that
the cap has been dislodged from the engagement position. A
combination cap and bottle is also provided.
